Packaging and Accessories

• 

• 

Arriving in a small blue and white box the Yinyoo V2 has fairly basic packaging. On the front are some renders of the monitors and on the back are the specifications.

Inside the box is a warranty card and a branded zipper case. The case is semi-rigid and perfect for protecting the monitors. Inside is the V2 and other accessories. Here’s what you get in total:

• Yinyoo V2 IEM
• 3x pairs of white silicone eartips (S, M, L)
• 3x pairs of grey silicone eartips (S, M, L)
• Detachable 0.75mm 2-pin cable
• Zipper case
• Warranty card

The 2 sets of eartips differ only in colour which makes a second set almost redundant. While it is nice to have spares, it would be much more useful to have 2 different types, for example: one set with wide bores and one with narrow bores. In the end it doesn’t matter much for me because all 6 pairs are too small for my ear canals.

However, the bundle that comes with the Yinyoo V2 is quite good and the quality zipper case is a nice touch. Overall it’s a solid package.

Build Quality and Design

Anyone familiar with the Tin Audio T2 will have most likely noticed the similarity in the earphone housings. Yes, the V2’s design has clearly been borrowed from the T2 but they both have a different driver setup.

At first glance, the two IEMs look identical but there are some significant differences in the housings. The V2’s body is slimmer and it has a large vent on the faceplate that has been cut out in the shape of the brand logo. Also, the raised section on the faceplate is a teardrop shape compared to the T2’s circular one.

I’m not going to dwell on the similarities. There will surely be a few reading who are upset by the appearance but it doesn’t bother me. I’m interested in the comfort, sound and relative value for money. For all we know, the 2 IEMs may have come from the same OEM.

So, with that out of the way, the V2 is extremely lightweight and very nicely built. Like several other budget earphones we’ve seen recently the Yinyoo V2 has the increasingly popular 2-pin connectors.

There’s a good ridge on the nozzle that works well to hold eartips on snugly and also present is a metal mesh covering the nozzle to prevent earwax and debris from infiltrating the housing.

Cable

Accompanying the V2 is a 4-core silver-plated cable. It has a clear TPU exterior and comes in a twisted format. The cable is sufficiently supple and sits well. It does have some microphonics if worn in the down style but this can be almost entirely eliminated by wearing the cable over-ear.

The metal 2-pin connectors perfectly match the colour of the IEM’s housings and are labeled with an L and R to identify left and right consecutively. There is also a tiny little blue dot on each connector to help make sure you get the correct alignment and polarity.

Further down the cable is a small cylindrical Y-split with Yinyoo branding on one side. There is no chin slider which is a bit of a shame. The cable terminates with a straight metal plug, again with the Yinyoo branding and a solid strain relief.

Comfort and Noise Isolation

Comfort is very good whether the earphones are worn down or over-ear. They’re quite small and very lightweight and can easily be worn for long listening sessions.

Noise isolation is only average but for most environments should be perfectly fine. With music playing at a fairly low volume I can’t hear my TV over the other side of the room. Noise leak is also minimal so shouldn’t be a concern.

Sound

Gear used for testing includes the Shanling M0 and Sony NW-ZX300 performing DAP duty on the go. On the desktop is my Windows PC running Tidal Hifi or JRiver Media Center and feeding the Topping DX7 DAC.

The Yinyoo V2 has a balanced signature with some emphasis on the low end. It’s warm, engaging and airy without any sharpness or unwanted peaks. This is one of those earphones that makes you want to turn the music up loud.

Bass

Punchy and organic, the V2’s bass is really nicely done. Its medium-paced attack and decay give drums a natural presence. The bass feels powerful but never tiring or excessive. The IEMs metal housings do a good job of ensuring there is no unwanted resonance and keep things under tight control.

The V2 sub-bass extends well and gives things a good shake-up when needed but it does start to fall off pretty quickly from around 40Hz. The majority of the body is found in the mid-bass and in tracks like Infected Mushroom’s “Groove Attack” the V2 really gets things going with an abundance of texture and energy.

Mids

There’s a little colour in the lower midrange that lends itself well to male vocals, giving them a richness without adversely affecting articulation. Female vocals get some extra body too and there are no hidden peaks to cause any unease. I can comfortably listen to Loreena McKennitt where on a lot of other earphones her high notes can get too shrill for my ears.

The electric guitars in “Trauma” by Long Distance Calling are gritty and textured and almost had me playing the air guitar in my chair. Things get more linear and closer to neutral as we move towards the upper midrange. Instrument separation and layering are solid and the tonal balance is pleasing with the midrange stepping up to the line with the treble and bass.

Treble

The V2’s treble is tuned well and finds a good balance between energy and smoothness.  It has sharpness and solidity and adds a good amount of air to the sound but avoids any harshness or stridency.

Portishead’s “Humming” can be downright punishing to the ears on a less refined IEM but the V2 makes it an easy listen without losing any of the vital details in the song.

Soundstage

What you get with the V2 is a stage that feels wider than it is deep. That’s not because the stage is shallow but rather because it’s wider than average. Imaging is strong and positional cues are clear and fairly accurate. The stage is stable, giving instruments and vocals ample density and solidity.

Comparisons

Yinyoo V2 vs BQEYZ K2 ($48 USD)

Both IEMs have a very similar amount of sub and mid-bass and are almost an exact match until the upper midrange (at least according to my measurements).

Arriving at the upper midrange the K2 (review here) becomes more prominent until it dips at 5kHz-6kHz. This gives female vocals some extra zing on the K2. The V2, in contrast, has a more linear rise but doesn’t have the same 9kHz peak that gives the K2 much of its extra clarity. The K2 has more upper treble energy and a similar amount of sparkle.

Both of these IEMs have good build quality but the Yinyoo requires less fuss to get a comfortable and stable fit in my ears.

Yinyoo V2 vs RevoNext QT2 ($46 USD)

The QT2 (review here) has a much more prominent sub-bass; it’s a real beast at the lower frequencies. Mid-bass levels are similar with both earphones showing good control and definition.

The QT2’s midrange is slightly more recessed making the V2 vocals sound more forward and intimate. Separation is better on the QT2 probably because of its larger driver count. Reaching into the treble the V2 has less sparkle but again displays its prowess with a smoother extension devoid of any harsh peaks.

Yinyoo V2 vs Tin Audio T2 ($49 USD)

I’m sure this is the comparison that most people will be interested in, simply because both IEMs look so much alike and the T2 (review here) has become somewhat of a fan favourite since its release.

Well, I won’t be surprised if the V2 becomes a favourite as well. It’s almost like the T2 with that extra bit of bass and body (like what many were hoping to get from the T2 Pro.) Obviously, the V2 has more bass, in particular, mid-bass. While the Yinyoo doesn’t feel quite as nimble in the mid-bass as the Tin Audio, its slower decay does sound more accurate. In the very low sub-bass, the fast rumble of the 2 monitors sound remarkably similar too. 

There’s some colouring and a hint of bass bleed in the V2’s lower midrange, whereas the T2 is more neutral throughout. However, as you get to the main and upper mids the two IEMs have a similar presentation but the V2 doesn’t have the same dryness thanks to its extra warmth and body.

Treble is similar on both but the V2 favours the lower treble more and the T2 has a smidge more harmonics in the upper treble.

Conclusion

Coming in at around $49 (or $39 with our special discount) the Yinyoo V2 provides a great sound and good value. It’s certainly better than what I was expecting for the price. Considering the quality of the audio, well-built alloy housings, detachable cable and zipper case this is a really well-rounded bundle and I recommend you grab one for yourself.
